Dopamine (5-20 mics/kg/min) as a positive inotrope (dopaminergic, alpha and beta agonist activity) and norepinephrine (0.1-0.5 mics/kg/min) as a vasopressor (alpha agonist) are used for increasing blood pressure. The goal will be to maintain a mean arterial pressure (DBP plus 1/3 rd of pulse pressure) of > 60 mm Hg.
